Rescues · TO CHAR
Charred outside, raw inside, on something thick.
Why it happens
Correct for a pepper you are going to peel, wrong for anything eaten whole. Match the technique to whether the interior needs cooking.
Recovering it
Over-charred skin on peppers, aubergines and tomatoes is entirely recoverable, because the skin is discarded — that is the design. Over-charred food that will be eaten skin and all cannot be fixed; scrape what you can and accept a smokier dish than intended. Under-charred is easy: more heat, and take half the food out so the pan can recover.
The mechanism
Char sits past browning. Maillard reactions and caramelisation give sweetness and depth; pyrolysis — the thermal breakdown of the food itself — gives smoke, bitterness and a set of compounds nothing else produces. Used as a whole-surface treatment that is a mistake, but used in patches against unburnt food it reads as smoke and complexity rather than as burning. That contrast is the entire technique: a fajita pepper blistered black in spots against green flesh, a tortilla with dark freckles, an aubergine burnt entirely on the outside so the flesh inside tastes of smoke. It works because the bitter compounds stay concentrated at the surface while the flavour they contribute disperses. Charring also demands a dry surface and real heat — food that is wet or on a moderate flame goes grey and steams long before it can blacken.
